Chemical kinetics
rate (kinetics) Kinetics: Rate. Chemical Kinetics - The study of the rates of chemical reactions. Rate of a Reaction - The change in concentration of one of the reactants (DX), during a given period of time (Dt) The reaction rate gradually decreases as reactants are consumed.

Reaction rate(average rates and Instantenous rates)
Reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

Rate laws
Because the rate of a reaction has dimensions of concentration per unit time, the dimensions of the rate constant k depend on the exponents of the concentration terms in the rate law. If p is the sum of the exponents of the concentration terms in the rate law, p=a b

Activation energy calculations
Step 1: Convert temperatures from degrees Celsius to Kelvin. T = degrees Celsius 273.15. T1 = 3 273.15. ... Step 2 - Find Ea ln(k2/k1) = Ea/R x (1/T1 - 1/T2) ln(7.1 x 10-2/8.9 x 10-3) = Ea/8.3145 J/K·mol x (1/276.15 K - 1/308.15 K) ... Answer: The activation energy for this reaction is 4.59 x 104 J/mol or 45.9 kJ/mol.

Intergrated rate laws
The rate law is a differential equation, meaning that it describes the change in concentration of reactant(s) per change in time. Using calculus, the rate law can be integrated to obtain an integrated rate equation that links concentrations of reactants or products with time directly.

Half life reactions
The half-life of a reaction, t1/2, is the amount of time needed for a reactant concentration to decrease by half compared to its initial concentration. Its application is used in chemistry and medicine to predict the concentration of a substance over time.

Rate constants and Order of reactions
k is the first-order rate constant, which has units of 1/s. The method of determining the order of a reaction is known as the method of initial rates. The overall order of a reaction is the sum of all the exponents of the concentration terms in the rate equation.
